Definitions
- Perlite products are often prepared by milling and thermal expansion, and possess unique physical properties such as high porosity, low bulk density, and chemical inertness. Depending on their quality and processing, perlite products are used as filter aids, lightweight insulating materials, filler materials, and chemical carriers. Expanded perlite has been used in filtration applications since about the late 1940's (Breese and Barker,
